II. INTRODUCTION

A. Field

The present invention relates to compounds, prodrugs, and methods ofusing these compounds and prodrugs thereof in the treatment ofconditions in which modulation of the JAK pathway or inhibition of JAKkinases, particularly JAK3, are therapeutically useful.

B. Background

Protein kinases constitute a large family of structurally relatedenzymes that are responsible for the control of a variety of signaltransduction processes within cells (see, e.g., Hardie and Hanks, TheProtein Kinase Facts Book, I and II, Academic Press, San Diego, Calif.,1995). Protein kinases are thought to have evolved from a commonancestral gene due to the conservation of their structure and catalyticfunction. Almost all kinases contain a similar 250-300 amino acidcatalytic domain. The kinases can be categorized into families by thesubstrates they phosphorylate (e.g., protein-tyrosine,protein-serine/threonine, lipids, etc.). Sequence motifs have beenidentified that generally correspond to each of these families (see,e.g., Hanks & Hunter, (1995), FASEB J. 9:576-596; Knighton et al.,(1991), Science 253:407-414; Hiles et al., (1992), Cell 70:419-429; Kunzet al., (1993), Cell 73:585-596; Garcia-Bustos et al., (1994), EMBO J.13:2352-2361).

JAK kinases (JAnus Kinases) are a family of cytoplasmic protein tyrosinekinases including JAK1, JAK2, JAK3 and TYK2. Each of the JAK kinases isselective for the receptors of certain cytokines, though multiple JAKkinases can be affected by particular cytokine or signaling pathways.Studies suggest that JAK3 associates with the common gamma (γc) chain ofthe various cytokine receptors. JAK3 in particular selectively binds toreceptors and is part of the cytokine signaling pathway for IL-2, IL-4,IL-7, IL-9, IL-15 and IL-21. JAK1 interacts with, among others, thereceptors for cytokines IL-2, IL-4, IL-7, IL-9 and IL-21, while JAK2interacts with, among others, the receptors for IL-9 and TNF-α. Upon thebinding of certain cytokines to their receptors (e.g., IL-2, IL-4, IL-7,IL-9, IL-15 and IL-21), receptor oligomerization occurs, resulting inthe cytoplasmic tails of associated JAK kinases being brought intoproximity and facilitating the trans-phosphorylation of tyrosineresidues on the JAK kinase. This trans-phosphorylation results in theactivation of the JAK kinase.

Phosphorylated JAK kinases bind various STAT (Signal Transducer andActivator of Transcription) proteins. STAT proteins, which are DNAbinding proteins activated by phosphorylation of tyrosine residues,function both as signaling molecules and transcription factors andultimately bind to specific DNA sequences present in the promoters ofcytokine-responsive genes (Leonard et al., (2000), J. Allergy Clin.Immunol. 105:877-888). JAK/STAT signaling has been implicated in themediation of many abnormal immune responses such as allergies, asthma,autoimmune diseases such as transplant (allograft) rejection, rheumatoidarthritis, amyotrophic lateral sclerosis and multiple sclerosis, as wellas in solid and hematologic malignancies such as leukemia and lymphomas.For a review of the pharmaceutical intervention of the JAK/STAT pathwaysee Frank, (1999), Mol. Med. 5:432:456 and Seidel et al., (2000),Oncogene 19:2645-2656.

JAK3 in particular has been implicated in a variety of biologicalprocesses. For example, the proliferation and survival of murine mastcells induced by IL-4 and IL-9 have been shown to be dependent onJAK3-and gamma chain-signaling (Suzuki et al., (2000), Blood96:2172-2180). JAK3 also plays a crucial role in IgE receptor-mediatedmast cell degranulation responses (Malaviya et al., (1999), Biochem.Biophys. Res. Commun. 257:807-813), and inhibition of JAK3 kinase hasbeen shown to prevent type I hypersensitivity reactions, includinganaphylaxis (Malaviya et al., (1999), J. Biol. Chem. 274:27028-27038).JAK3 inhibition has also been shown to result in immune suppression forallograft rejection (Kirken, (2001), Transpl. Proc. 33:3268-3270). JAK3kinases have also been implicated in the mechanism involved in early andlate stages of rheumatoid arthritis (Muller-Ladner et al., (2000), J.Immunal. 164:3894-3901); familial amyotrophic lateral sclerosis (Trieuet al., (2000), Biochem Biophys. Res. Commun. 267:22-25); leukemia(Sudbeck et al., (1999), Clin. Cancer Res. 5:1569-1582); mycosisfungoides, a form of T-cell lymphoma (Nielsen et al., (1997), Prac.Natl. Acad. Sci. USA 94:6764-6769); and abnormal cell growth (Yu et al.,(1997), J. Immunol. 159:5206-5210; Catlett-Falcone et al., (1999),Immunity 10:105-115).

The JAK kinases, including JAK3, are abundantly expressed in primaryleukemic cells from children with acute lymphoblastic leukemia, the mostcommon form of childhood cancer, and studies have correlated STATactivation in certain cells with signals regulating apoptosis (Demoulinet al., (1996), Mol. Cell. Biol. 16:4710-6; Jurlander et al., (1997),Blood. 89:4146-52; Kaneko et al., (1997), Clin. Exp. Immun. 109:185-193;and Nakamura et al.,(1996), J. Biol. Chem. 271:19483-8). They are alsoknown to be important to lymphocyte differentiation, function andsurvival. JAK-3 in particular plays an essential role in the function oflymphocytes, macrophages, and mast cells. Given the importance of thisJAK kinase, compounds which modulate the JAK pathway, including thoseselective for JAK3, can be useful for treating diseases or conditionswhere the function of lymphocytes, macrophages, or mast cells isinvolved (Kudlacz et al., (2004) Am. J. Transplant 4:51-57; Changelian(2003) Science 302:875-878). Conditions in which targeting of the JAKpathway or modulation of the JAK kinases, particularly JAK3, arecontemplated to be therapeutically useful include, leukemia, lymphoma,transplant rejection (e.g., pancreas islet transplant rejection, bonemarrow transplant applications (e.g., graft-versus-host disease),autoimmune diseases (e.g., diabetes), and inflammation (e.g., asthma,allergic reactions). Conditions which can benefit for inhibition of JAK3are discussed in greater detail below.

In view of the numerous conditions that are contemplated to benefit bytreatment involving modulation of the JAK pathway it is immediatelyapparent that new compounds that modulate JAK pathways and methods ofusing these compounds should provide substantial therapeutic benefits toa wide variety of patients. Provided herein are novel2,4-pyrimidinediamine compounds for use in the treatment of conditionsin which targeting of the JAK pathway or inhibition of JAK kinases,particularly JAK3, are therapeutically useful.

“Tautomer” refers to alternate forms of a molecule that differ in theposition of a proton, such as enol-keto and imine-enamine tautomers, orthe tautomeric forms of heteroaryl groups containing a —N═C(H)—NH— ringatom arrangement, such as pyrazoles, imidazoles, benzimidazoles,triazoles, and tetrazoles. A person of ordinary skill in the art wouldrecognize that other tautomeric ring atom arrangements are possible.

“Patient” refers to human and non-human animals, especially mammals.

“Pharmaceutically acceptable salt” refers to pharmaceutically acceptablesalts of a compound, which salts are derived from a variety of organicand inorganic counter ions well known in the art and include, by way ofexample only, sodium, potassium, calcium, magnesium, ammonium,tetraalkylammonium, and the like; and when the molecule contains a basicfunctionality, salts of organic or inorganic acids, such ashydrochloride, hydrobromide, tartrate, mesylate, acetate, maleate,oxalate, and the like.

“Prodrug” refers to a derivative of an active 4-pyrimidineamine compound(drug) that may require a transformation under the conditions of use,such as within the body, to release the active 2,4-pyrimidinediaminedrug. Prodrugs are frequently, but not necessarily, pharmacologicallyinactive until converted into the active drug. Prodrugs are typicallyobtained by masking one or more functional groups in an active2,4-pyrimidinediamine drug believed to be in part required for activitywith a progroup (defined below) to form a promoiety which undergoes atransformation, such as cleavage, under the specified conditions of useto release the functional group, and hence the active2,4-pyrimidinediamine drug. The cleavage of the promoiety may proceedspontaneously, such as by way of a hydrolysis reaction, or it can becatalyzed or induced by another agent, such as an enzyme, light, an acidor base, or a change of or exposure to a physical or environmentalparameter, such as temperature. The agent can be endogenous to theconditions of use, such as an enzyme present in the cells to which theprodrug is administered or the acidic conditions of the stomach, or itcan be supplied exogenously.

“Progroup” refers to a type of protecting group that, when used to maska functional group within an active 2,4-pyrimidinediamine drug to form apromoiety, converts the drug into a prodrug. Progroups are typicallyattached to the functional group of the drug via bonds that arecleavable under specified conditions of use. Thus, a progroup is thatportion of a promoiety that cleaves to release the functional groupunder the specified conditions of use. As a specific example, an amidepromoiety of the formula —NH—C(O)CH₃ comprises the progroup —C(O)CH₃.

Those of skill in the art will appreciate that the 2,4-pyrimidinediaminecompounds described herein may include functional groups that can bemasked with progroups to create prodrugs. Such prodrugs are usually, butneed not be, pharmacologically inactive until converted into theiractive drug form. Indeed, many of the 2,4-pyrimidinediamine compoundsdescribed in this invention include promoieties that are hydrolyzable orotherwise cleavable under conditions of use. For example, ester groupscommonly undergo acid-catalyzed hydrolysis to yield the parentcarboxylic acid when exposed to the acidic conditions of the stomach orbase-catalyzed hydrolysis when exposed to the basic conditions of theintestine or blood. Thus, when administered to a subject orally,2,4-pyrimidinediamine compounds that include ester moieties can beconsidered prodrugs of their corresponding carboxylic acid, regardlessof whether the ester form is pharmacologically active.

The mechanism by which the progroup(s) metabolizes is not critical andcan be caused, for example, by hydrolysis under the acidic conditions ofthe stomach, as described above, and/or by enzymes present in thedigestive tract and/or tissues or organs of the body. Indeed, theprogroup(s) can be selected to metabolize at a particular site withinthe body. For example, many esters are cleaved under the acidicconditions found in the stomach. Prodrugs designed to cleave chemicallyin the stomach to the active 2,4-pyrimidinediamine can employ progroupsincluding such esters. Alternatively, the progroups can be designed tometabolize in the presence of enzymes such as esterases, amidases,lipolases, and phosphatases, including ATPases and kinase, etc.Progroups including linkages capable of metabolizing in vivo are wellknown and include, by way of example and not limitation, ethers,thioethers, silylethers, silylthioethers, esters, thioesters,carbonates, thiocarbonates, carbamates, thiocarbamates, ureas,thioureas, and carboxamides. In some instances, a “precursor” group thatis oxidized by oxidative enzymes such as, for example, cytochrome P450of the liver, to a metabolizable group, can be selected.

In the prodrugs, any available functional moiety can be masked with aprogroup to yield a prodrug. Functional groups within the2,4-pyrimidinediamine compounds that can be masked with progroups forinclusion in a promoiety include, but are not limited to, amines(primary and secondary), hydroxyls, sulfanyls(thiols), and carboxyls. Awide variety of progroups, as well as the resultant promoieties,suitable for masking functional groups in active 2,4-pyrimidinediaminecompounds to yield prodrugs are well-known in the art. For example, ahydroxyl functional group can be masked as a sulfonate, ester, orcarbonate promoiety, which can be hydrolyzed in vivo to provide thehydroxyl group. An amino functional group can be masked as an amide,carbamate, imine, urea, phosphenyl, phosphoryl, or sulfenyl promoiety,which can be hydrolyzed in vivo to provide the amino group. A carboxylgroup can be masked as an ester (including silyl esters and thioesters),amide, or hydrazide promoiety, which can be hydrolyzed in vivo toprovide the carboxyl group. Other specific examples of suitableprogroups and their respective promoieties will be apparent to those ofskill in the art. All of these progroups, alone or in combinations, canbe included in the prodrugs.

In some embodiments of the 2,4-pyrimidinediamine compounds and methodsof using the compounds, the progroup(s) can be attached to any availableprimary or secondary amine, including, for example, the N2 nitrogen atomof the 2,4-pyrimidinediamine moiety, the N4 nitrogen atom of the2,4-pyrimidinediamine moiety, and/or a primary or secondary nitrogenatom included in a substituent on the 2,4-pyrimidinediamine compound.

In particular embodiments of the 2,4-pyrimidinediamine compounds andmethods of using the compounds, the prodrugs described herein are2,4-pyrimidinediamine compounds that are substituted at the N4 nitrogenof the 2,4-pyrimidinediamine moiety with a substituted or unsubstitutednitrogen-containing bicyclic ring that includes at least one progroup atone or more of the following: the nitrogen atom(s) of the bicyclic ring,the N2 nitrogen of the 2,4-pyrimidinediamine moiety, and the N4 nitrogenof the 2,4-pyrimidinediamine moiety.

As noted above, the identity of the progroup is not critical, providedthat it can be metabolized under the desired conditions of use, forexample, under the acidic conditions found in the stomach and/or byenzymes found in vivo, to yield a biologically active group, e.g., the2,4-pyrimidinediamines as described herein. Thus, skilled artisans willappreciate that the progroup can comprise virtually any known orlater-discovered hydroxyl, amine or thiol protecting group. Non-limitingexamples of suitable protecting groups can be found, for example, inProtective Groups in Organic Synthesis, Greene & Wuts, 2nd Ed., JohnWiley & Sons, New York, 1991 (especially pages 10-142 (alcohols, 277-308(thiols) and 309-405 (amines) the disclosure of which is incorporatedherein by reference).

Additionally, the identity of the progroup(s) can also be selected so asto impart the prodrug with desirable characteristics. For example,lipophilic groups can be used to decrease water solubility andhydrophilic groups can be used to increase water solubility. In thisway, prodrugs specifically tailored for selected modes of administrationcan be obtained. The progroup can also be designed to impart the prodrugwith other properties, such as, for example, improved passive intestinalabsorption, improved transport-mediated intestinal absorption,protection against fast metabolism (slow-release prodrugs),tissue-selective delivery, passive enrichment in target tissues, andtargeting-specific transporters. Groups capable of imparting prodrugswith these characteristics are well-known and are described, forexample, in Ettmayer et al., 2004, J. Med. Chem. 47(10):2393-2404, thedisclosure of which is incorporated by reference. All of the variousgroups described in these references can be utilized in the prodrugsdescribed herein.

As noted above, progroup(s) may also be selected to increase the watersolubility of the prodrug as compared to the active drug. Thus, theprogroup(s) may include or can be a group(s) suitable for imparting drugmolecules with improved water solubility. Such groups are well-known andinclude, by way of example and not limitation, hydrophilic groups suchas alkyl, aryl, and arylalkyl, or cycloheteroalkyl groups substitutedwith one or more of an amine, alcohol, a carboxylic acid, a phosphorousacid, a sulfoxide, a sugar, an amino acid, a thiol, a polyol, an ether,a thioether, and a quaternary amine salt.

The suitability of any particular progroup for a desired mode ofadministration can be confirmed in biochemical assays. For example, if aprodrug is to be administered by injection into a particular tissue ororgan and the identities of the various enzyme(s) expressed in thetissue or organ are known, the particular prodrug can be tested formetabolism in biochemical assays with the isolated enzyme(s).Alternatively, the particular prodrug can be tested for metabolism tothe active 2,4-pyrimidinediamine compound with tissue and/or organextracts. Using tissue and/or organ extracts can be of particularconvenience when the identity(ies) of the enzymes expressed in thetarget tissues or organs are unknown or in instances when the isolatedenzymes are not conveniently available. Skilled artisans will be able toreadily select progroups having metabolic properties (such as kinetics)suitable for particular applications using such in vitro tests. Ofcourse, specific prodrugs could also be tested for suitable metabolismin vitro animal models.

Numerous references teach the use and synthesis of prodrugs, including,for example, Ettmayer et al., supra and Bungaard et al., (1989) J. Med.Chem. 32(12): 2503-2507. Additionally, the preparation and use ofprodrugs of 2,4-pyrimidinediamines is specifically taught in U.S.Provisional Patent Application 60/654,620, filed Feb. 18, 2005, entitled“Pyrimidinediamine Prodrugs and their Uses,” the disclosure of which ishereby incorporated by reference in its entirety.

One of ordinary skill in the art will appreciate that many of thecompounds and prodrugs thereof, as well as the various compound speciesspecifically described and/or illustrated herein, may exhibit thephenomena of tautomerism, conformational isomerism, geometric isomerism,and/or optical isomerism. For example, the compounds and prodrugs of theinvention may include one or more chiral centers and/or double bonds andas a consequence may exist as stereoisomers, such as double-bond isomers(i.e., geometric isomers), enantiomers, diasteromers, and mixturesthereof, such as racemic mixtures. As another example, the compounds andprodrugs of the invention may exist in several tautomeric forms,including the enol form, the keto form, and mixtures thereof. As thevarious compound names, formulae and compound drawings within thespecification and claims can represent only one of the possibletautomeric, conformational isomeric, optical isomeric, or geometricisomeric forms, it should be understood that the invention encompassesany tautomeric, conformational isomeric, optical isomeric, and/orgeometric isomeric forms of the compounds or prodrugs having one or moreof the utilities described herein, as well as mixtures of these variousdifferent isomeric forms. In cases of limited rotation around the2,4-pryimidinediamine core structure, atropisomers are also possible andare also specifically included in the compounds of the invention. It isintended that the compounds encompassed herein are, with the exceptionof forms of isomerism, chemically stable and able to be isolated.

D. Methods of the Invention

The present invention provides 2,4-pyrimidinediamine compounds andprodrugs thereof, as described herein, for use in therapy for theconditions described herein. The present invention further provides useof the compounds of the present invention in the manufacture of amedicament for the treatment of conditions in which targeting of the JAKpathway or inhibition of JAK kinases, particularly JAK3, aretherapeutically useful. These include conditions where the function oflymphocytes, macrophages, or mast cells is involved. Conditions in whichtargeting of the JAK pathway or inhibition of the JAK kinases,particularly JAK3, are therapeutically useful include leukemia,lymphoma, transplant rejection (e.g., pancreas islet transplantrejection), bone marrow transplant applications (e.g., graft-versus-hostdisease)), autoimmune diseases (e.g., rheumatoid arthritis, etc.),inflammation (e.g., asthma, etc.) and other conditions as described ingreater detail herein.

As noted previously, numerous conditions can be treated using the2,4-substituted pyrimidinediamine compounds, prodrugs thereof, andmethods of treatment as described herein. As used herein, “Treating” or“treatment” of a disease in a patient refers to (1) preventing thedisease from occurring in a patient that is predisposed or does not yetdisplay symptoms of the disease; (2) inhibiting the disease or arrestingits development; or (3) ameliorating or causing regression of thedisease. As well understood in the art, “treatment” is an approach forobtaining beneficial or desired results, including clinical results. Forthe purposes of this invention, beneficial or desired results caninclude one or more, but are not limited to, alleviation or ameliorationof one or more symptoms, diminishment of extent of a condition,including a disease, stabilized (i.e., not worsening) state of acondition, including diseases, preventing spread of disease, delay orslowing of condition, including disease, progression, amelioration orpalliation of the condition, including disease, state, and remission(whether partial or total), whether detectable or undetectable.Preferred are compounds that are potent and can be administered locallyat very low doses, thus minimizing systemic adverse effects.

The compounds described herein are potent and selective inhibitors ofJAK kinases and are particularly selective for cytokine signalingpathways containing JAK3. As a consequence of this activity, thecompounds can be used in a variety of in vitro, in vivo, and ex vivocontexts to regulate or inhibit JAK kinase activity, signaling cascadesin which JAK kinases play a role, and the biological responses effectedby such signaling cascades. For example, in one embodiment, thecompounds can be used to inhibit JAK kinase, either in vitro or in vivo,in virtually any cell type expressing the JAK kinase, such as inhematopoietic cells in which, for example, JAK3 is predominantlyexpressed. They may also be used to regulate signal transductioncascades in which JAK kinases, particularly JAK3, play a role. SuchJAK-dependent signal transduction cascades include, but are not limitedto, the signaling cascades of cytokine receptors that involve the commongamma chain, such as, for example, the IL-4, IL-7, IL-5, IL-9, IL-15 andIL-21, or IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21 receptor signalingcascades. The compounds may also be used in vitro or in vivo toregulate, and in particular to inhibit, cellular or biological responsesaffected by such JAK-dependent signal transduction cascades. Suchcellular or biological responses include, but are not limited to,IL-4/ramos CD23 upregulation and IL-2 mediated T-cell proliferation.Importantly, the compounds can be used to inhibit JAK kinases in vivo asa therapeutic approach towards the treatment or prevention of diseasesmediated, either wholly or in part, by a JAK kinase activity (referredto herein as “JAK kinase mediated diseases”). Non-limiting examples ofJAK kinase mediated diseases that can be treated or prevented with thecompounds include, but are not limited to, the following: allergies;asthma; autoimmune diseases such as transplant rejection (e.g., kidney,heart, lung, liver, pancreas, skin, small intestine, large intestine,host versus graft reaction (HVGR), and graft versus host reaction(GVHR)), rheumatoid arthritis, and amyotrophic lateral sclerosis; T-cellmediated autoimmune diseases such as multiple sclerosis, psoraiasis, andSjogren's syndrome; Type II inflammatory diseases such as vascularinflammation (including vasculitis, arteritis, atherosclerosis, andcoronary artery disease); diseases of the central nervous system such asstroke; pulmonary diseases such as bronchitis obliteraus and primarypulmonary hypertension; solid, delayed Type IV hypersensitivityreactions; and hematologic malignancies such as leukemia and lymphomas.

Examples of diseases that are mediated, at least in part, by JAK kinasesthat can be treated or prevented according to the methods include, butare not limited to, allergies, asthma, autoimmune diseases such astransplant rejection (e.g., kidney, heart, lung, liver, pancreas, skin,host versus graft reaction (HVGR), etc.), rheumatoid arthritis, andamyotrophic lateral sclerosis, multiple sclerosis, psoraiasis andSjogren's syndrome, Type II inflammatory disease such as vascularinflammation (including vasculitis, ateritis, atherosclerosis andcoronary artery disease) or other inflammatory diseases such asosteoarthritis, inflammatory bowel disease, ulcerative colitis, Crohn'sdisease, idiopathic inflammatory bowel disease, irritable bowelsyndrome, spastic colon, low grade scarring (e.g., scleroderma,increased fibrosis, keloids, post-surgical scars, pulmonary fibrosis,vascular spasms, migraine, reperfusion injury and post myocardialinfarction), and sicca complex or syndrome, diseases of the centralnervous system such as stroke, pulmonary diseases such as bronchitisobliterous and primary and primary pulmonary hypertension, delayed orcell-mediated, Type IV hypersensitivity and solid and hematologicmalignancies such as leukemias and lyphomas.

In another embodiment, this invention provides a method of inhibiting anactivity of a JAK kinase, comprising contacting the JAK kinase with anamount of a compound effective to inhibit an activity of the JAK kinase,wherein the compound is selected from the compounds of this invention.In certain embodiments of the methods described herein, the method iscarried out in vivo.

In another embodiment, this invention provides a method of inhibiting anactivity of a JAK kinase, comprising contacting in vitro a JAK3 kinasewith an amount of a compound effective to inhibit an activity of the JAKkinase, wherein the compound is selected from the compounds of thisinvention.

In a specific embodiment, the compounds can be used to treat and/orprevent rejection in organ and/or tissue transplant recipients (i.e.,treat and/or prevent allorgraft rejection). Allografts can be rejectedthrough either a cell-mediated or humoral immune reaction of therecipient against transplant (histocompability) antigens present on themembranes of the donor's cells. The strongest antigens are governed by acomplex of genetic loci termed human leukocyte group A (HLA) antigens.Together with the ABO blood groups antigens, they are the chieftransplantation antigens detectable in humans.

Rejection following transplantation can generally be broken into threecategories: hyperacute, occurring hours to days followingtransplantation; acute, occurring days to months followingtransplantation; and chronic, occurring months to years followingtransplantation.

Hyperacute rejection is caused mainly by the production of hostantibodies that attack the graft tissue. In a hyperacute rejectionreaction, antibodies are observed in the transplant vascular very soonafter transplantation. Shortly thereafter, vascular clotting occurs,leading to ischemia, eventual necrosis and death. The graft infarctionis unresponsive to known immunosuppressive therapies. Because HLAantigens can be identified in vitro, pre-transplant screening is used tosignificantly reduce hyperacute rejection. As a consequence of thisscreening, hyperacute rejection is relatively uncommon today.

Acute rejection is thought to be mediated by the accumulation of antigenspecific cells in the graft tissue. The T-cell-mediated immune reactionagainst these antigens (i.e., HVGR or GVHR) is the principle mechanismof acute rejection. Accumulation of these cells leads to damage of thegraft tissue. It is believed that both CD4+ helper T-cells and CD8+cytotoxic T-cells are involved in the process and that the antigen ispresented by donor and host dendritic cells. The CD4+ helper T-cellshelp recruit other effector cells, such as macrophages and eosinophils,to the graft. Accessing T-cell activation signal transduction cascades(for example, CD28, CD40L, and CD2 cascades) are also involved.

The cell-mediated acute rejection can be reversed in many cases byintensifying immunotherapy. After successful reversal, severely damagedelements of the graft heal by fibrosis and the remainder of the graftappears normal. After resolution of acute rejection, dosages ofimmunosuppressive drugs can be reduced to very low levels.

Chronic rejection, which is a particular problem in renal transplants,often progresses insidiously despite increased immunosuppressivetherapy. It is thought to be due, in large part, to cell-mediated TypeIV hypersensitivity. The pathologic profile differs from that of acuterejection. The arterial endothelium is primarily involved with extensiveproliferation that may gradually occlude the vessel lumen, leading toischemia, fibrosis, a thickened intima, and atherosclerotic changes.Chronic rejection is mainly due to a progressive obliteration of graftvasculature and resembles a slow, vasculitic process.

In Type IV hypersensitivity, CD8 cytotoxic T-cells and CD4 helper Tcells recognize either intracellular or extracellular synthesizedantigen when it is complexed, respectively, with either Class I or ClassII MHC molecules. Macrophages function as antigen-presenting cells andrelease IL-1, which promotes proliferation of helper T-cells. HelperT-cells release interferon gamma and IL-2, which together regulatedelayed hyperactivity reactions mediated by macrophage activation andimmunity mediated by T cells. In the case of organ transplant, thecytotoxic T-cells destroy the graft cells on contact.

Since JAK kinases play a critical role in the activation of T-cells, the2,4-pyrimidinediamine compounds described herein can be used to treatand/or prevent many aspects of transplant rejection, and areparticularly useful in the treatment and/or prevention of rejectionreactions that are mediated, at least in part, by T-cells, such as HVGRor GVHR. The 2,4-pyrimidinediamine compounds can also be used to treatand/or prevent chronic rejection in transplant recipients and, inparticular, in renal transplant recipients. The compound can also beadministered to a tissue or an organ prior to transplanting the tissueor organ in the transplant recipient.

In another embodiment, this invention provides a method of treating aT-cell mediated autoimmune disease, comprising administering to apatient suffering from such an autoimmune disease an amount of acompound effective to treat the autoimmune disease wherein the compoundis selected from the compounds of the invention. In certain embodimentsof the methods the autoimmune disease is multiple sclerosis (MS),psoraisis, or Sjogran's syndrome. Such autoimmune disease include, butare not limited to, those autoimmune diseases that are frequentlydesignated as single organ or single cell-type autoimmune disorders andthose autoimmune disease that are frequently designated as involvingsystemic autoimmune disorder. Non-limiting examples of diseasesfrequently designated as single organ or single cell-type autoimmunedisorders include: Hashimoto's thyroiditis, autoimmune hemolytic anemia,autoimmune atrophic gastritis of pernicious anemia, autoimmuneencephalomyelitis, autoimmune orchitis, Goodpasture's disease,autoimmune thrombocytopenia, sympathetic ophthalmia, myasthenia gravis,Graves' disease, primary biliary cirrhosis, chronic aggressivehepatitis, ulcerative colitis and membranous glomerulopathy.Non-limiting examples of diseases often designated as involving systemicautoimmune disorder include: systemic lupus erythematosis, rheumatoidarthritis, Sjogren's syndrome, Reiter's syndrome,polymyositis-dermatomyositis, systemic sclerosis, polyarteritis nodosa,multiple sclerosis and bullous pemphigoid. Additional autoimmunediseases, which can be β-cell (humoral) based or T-cell based, includeCogan's syndrome, ankylosing spondylitis, Wegener's granulomatosis,autoimmune alopecia, Type I or juvenile onset diabetes, and thyroiditis.

The types of autoimmune diseases that may be treated or prevented withsuch prodrugs generally include those disorders involving tissue injurythat occurs as a result of a humoral and/or cell-mediated response toimmunogens or antigens of endogenous and/or exogenous origin. Suchdiseases are frequently referred to as diseases involving thenonanaphylactic (i.e., Type II, Type III and/or Type IV)hypersensitivity reactions.

Type I hypersensitivity reactions generally result from the release ofpharmacologically active substances, such as histamine, from mast and/orbasophil cells following contact with a specific exogenous antigen. Asmentioned above, such Type I reactions play a role in numerous diseases,including allergic asthma, allergic rhinitis, etc.

Type II hypersensitivity reactions (also referred to as cytotoxic,cytolytic complement-dependent or cell-stimulating hypersensitivityreactions) result when immunoglobulins react with antigenic componentsof cells or tissue, or with an antigen or hapten that has becomeintimately coupled to cells or tissue. Diseases that are commonlyassociated with Type II hypersensitivity reactions include, but are notlimited, to autoimmune hemolytic anemia, erythroblastosis fetalis andGoodpasture's disease.

Type III hypersensitivity reactions, (also referred to as toxic complex,soluble complex, or immune complex hypersensitivity reactions) resultfrom the deposition of soluble circulating antigen-immunoglobulincomplexes in vessels or in tissues, with accompanying acute inflammatoryreactions at the site of immune complex deposition. Non-limitingexamples of prototypical Type III reaction diseases include the Arthusreaction, rheumatoid arthritis, serum sickness, systemic lupuserythematosis, certain types of glomerulonephritis, multiple sclerosisand bullous pemphingoid.

Type IV hypersensitivity reactions (frequently called cellular,cell-mediated, delayed, or tuberculin-type hypersensitivity reactions)are caused by sensitized T-lymphocytes which result from contact with aspecific antigen. Non-limiting examples of diseases cited as involvingType IV reactions are contact dermatitis and allograft rejection.

Autoimmune diseases associated with any of the above nonanaphylactichypersensitivity reactions may be treated or prevented with the prodrugsaccording to structural formulae (I) and (Ia). In particular, themethods may be used to treat or prevent those autoimmune diseasesfrequently characterized as single organ or single cell-type autoimmunedisorders including, but not limited to: Hashimoto's thyroiditis,autoimmune hemolytic anemia, autoimmune atrophic gastritis of perniciousanemia, autoimmune encephalomyelitis, autoimmune orchitis, Goodpasture'sdisease, autoimmune thrombocytopenia, sympathetic ophthalmia, myastheniagravis, Graves' disease, primary biliary cirrhosis, chronic aggressivehepatitis, ulcerative colitis and membranous glomerulopathy, as well asthose autoimmune diseases frequently characterized as involving systemicautoimmune disorder, which include but are not limited to: systemiclupus erythematosis (SLE), rheumatoid arthritis, Sjogren's syndrome,Reiter's syndrome, polymyositis-dermatomyositis, systemic sclerosis,polyarteritis nodosa, multiple sclerosis and bullous pemphigoid.

It will be appreciated by skilled artisans that many of the above-listedautoimmune diseases are associated with severe symptoms, theamelioration of which provides significant therapeutic benefit even ininstances where the underlying autoimmune disease may not beameliorated.

Therapy using the 2,4-pyrimidinediamine compounds described herein canbe applied alone, or it can be applied in combination with or adjunctiveto other common immunosuppressive therapies, such as, for example, thefollowing: mercaptopurine; corticosteroids such as prednisone;methylprednisolone and prednisolone; alkylating agents such ascyclophosphamide; calcineurin inhibitors such as cyclosporine,sirolimus, and tacrolimus; inhibitors of inosine monophosphatedehydrogenase (IMPDH) such as mycophenolate, mycophenolate mofetil, andazathioprine; and agents designed to suppress cellular immunity whileleaving the recipient's humoral immunologic response intact, includingvarious antibodies (for example, antilymphocyte globulin (ALG),antithymocyte globulin (ATG), monoclonal anti-T-cell antibodies (OKT3))and irradiation. These various agents can be used in accordance withtheir standard or common dosages, as specified in the prescribinginformation accompanying commercially available forms of the drugs (seealso: the prescribing information in the 2006 Edition of The Physician'sDesk Reference), the disclosures of which are incorporated herein byreference. Azathioprine is currently available from SalixPharmaceuticals, Inc., under the brand name AZASAN; mercaptopurine iscurrently available from Gate Pharmaceuticals, Inc., under the brandname PURINETHOL; prednisone and prednisolone are currently availablefrom Roxane Laboratories, Inc.; Methyl prednisolone is currentlyavailable from Pfizer; sirolimus (rapamycin) is currently available fromWyeth-Ayerst under the brand name RAPAMUNE; tacrolimus is currentlyavailable from Fujisawa under the brand name PROGRAF; cyclosporine iscurrent available from Novartis under the brand dame SANDIMMUNE and fromAbbott under the brand name GENGRAF; IMPDH inhibitors such asmycophenolate mofetil and mycophenolic acid are currently available fromRoche under the brand name CELLCEPT and from Novartis under the brandname MYFORTIC; azathioprine is currently available from Glaxo SmithKline under the brand name IMURAN; and antibodies are currentlyavailable from Ortho Biotech under the brand name ORTHOCLONE, fromNovartis under the brand name SIMULECT (basiliximab), and from Rocheunder the brand name ZENAPAX (daclizumab).

In another embodiment, the 2,4-pyrimidinediamine compounds could beadministered either in combination or adjunctively with an inhibitor ofa Syk kinase. Syk kinase is a tyrosine kinase known to play a criticalrole in Fcγ receptor signaling, as well as in other signaling cascades,such as those involving B-Cell receptor signaling (Tumer et al., (2000),Immunology Today 21:148-154) and integrins beta(1), beta (2), and beta(3) in neutrophils (Mocsavi et al., (2002), Immunity 16:547-558). Forexample, Syk kinase plays a pivotal role in high affinity IgE receptorsignaling in mast cells that leads to activation and subsequent releaseof multiple chemical mediators that trigger allergic attacks. However,unlike the JAK kinases, which help regulate the pathways involved indelayed or cell-mediated Type IV hypersensitivity reactions, Syk kinasehelps regulate the pathways involved in immediate IgE-mediated, Type Ihypersensitivity reactions. Certain compounds that affect the Sykpathway may or may not also affect the JAK pathways.

Suitable Syk inhibitory compounds are described, for example, in Ser.No. 10/355,543 filed Jan. 31, 2003 (publication no. 2004/0029902); WO03/063794; Ser. No. 10/631,029 filed Jul. 29, 2003; WO 2004/014382; Ser.No. 10/903,263 filed Jul. 30, 2004; PCT/US2004/24716 filed Jul. 30, 2004(WO005/016893); Ser.

No. 60/654,620,filed Feb. 18, 2005, the disclosures of which are incorporated herein byreference. The 2,4-pyrimidinediamine described herein and Syk inhibitorycompounds could be used alone or in combination with one or moreconventional transplant rejection treatments, as described above.

“Cell proliferative disorder” refers to a disorder characterized byabnormal proliferation of cells. A proliferative disorder does not implyany limitation with respect to the rate of cell growth, but merelyindicates loss of normal controls that affect growth and cell division.Thus, in some embodiments, cells of a proliferative disorder can havethe same cell division rates as normal cells but do not respond tosignals that limit such growth. Within the ambit of “cell proliferativedisorder” is neoplasm or tumor, which is an abnormal growth of tissue.Cancer refers to any of various malignant neoplasms characterized by theproliferation of cells that have the capability to invade surroundingtissue and/or metastasize to new colonization sites.

“Hematopoietic neoplasm” refers to a cell proliferative disorder arisingfrom cells of the hematopoietic lineage. Generally, hematopoiesis is thephysiological process whereby undifferentiated cells or stem cellsdevelop into various cells found in the peripheral blood. In the initialphase of development, hematopoietic stem cells, typically found in thebone marrow, undergo a series of cell divisions to form multipotentprogenitor cells that commit to two main developmental pathways: thelymphoid lineage and the myeloid lineage. The committed progenitor cellsof the myeloid lineage differentiate into three major sub-branchescomprised of the erythroid, megakaryocyte, and granulocyte/monocytedevelopmental pathways. An additional pathway leads to formation ofdendritic cells, which are involved in antigen presentation. Theerythroid lineage gives rise to red blood cells while the megakaryocyticlineage gives rise to blood platelets. Committed cells of thegranulocyte/monocyte lineage split into granulocyte or monocytedevelopmental pathways, the former pathway leading to formation ofneutrophils, eosinophils, and basophils and the latter pathway givingrise to blood monocytes and macrophages.

Committed progenitor cells of the lymphoid lineage develop into the Bcell pathway, T cell pathway, or the non-T/B cell pathway. Similar tothe myeloid lineage, an additional lymphoid pathway appears to give riseto dendritic cells involved in antigen presentation. The B cellprogenitor cell develops into a precursor B cell (pre-B), whichdifferentiates into B cells responsible for producing immunoglobulins.Progenitor cells of the T cell lineage differentiate into precursor Tcells (pre-T) that, based on the influence of certain cytokines, developinto cytotoxic or helper/suppressor T cells involved in cell mediatedimmunity. Non-T/B cell pathway leads to generation of natural killer(NK) cells. Neoplasms of hematopoietic cells can involve cells of anyphase of hematopoiesis, including hematopoietic stem cells, multipotentprogenitor cells, oligopotent committed progenitor cells, precursorcells, and mature differentiated cells. The categories of hematopoieticneoplasms can generally follow the descriptions and diagnostic criteriaemployed by those of skill in the art (see, e.g., InternationalClassification of Disease and Related Health Problems (ICD 10), WorldHealth Organization (2003)). Hematopoietic neoplasms can also becharacterized based on the molecular features, such as cell surfacemarkers and gene expression profiles, cell phenotype exhibited by theaberrant cells, and/or chromosomal aberrations (e.g., deletions,translocations, insertions, etc.) characteristic of certainhematopoietic neoplasms, such as the Philadelphia chromosome found inchronic myelogenous leukemia. Other classifications include NationalCancer Institute Working Formulation (Cancer, 1982, 49:2112-2135) andRevised European-American Lymphoma Classification (REAL).

“Lymphoid neoplasm” refers a proliferative disorder involving cells ofthe lymphoid lineage of hematopoiesis. Lymphoid neoplasms can arise fromhematopoietic stem cells as well as lymphoid committed progenitor cells,precursor cells, and terminally differentiated cells. These neoplasmscan be subdivided based on the phenotypic attributes of the aberrantcells or the differentiated state from which the abnormal cells arise.Subdivisions include, among others, B cell neoplasms, T cell neoplasms,NK cell neoplasms, and Hodgkin's lymphoma.

“Myeloid neoplasm” refers to proliferative disorder of cells of themyeloid lineage of hematopoiesis. Neoplasms can arise from hematopoieticstem cells, myeloid committed progenitor cells, precursor cells, andterminally differentiated cells. Myeloid neoplasms can be subdividedbased on the phenotypic attributes of the aberrant cells or thedifferentiated state from which the abnormal cells arise. Subdivisionsinclude, among others, myeloproliferative diseases,myelodysplastic/myeloproliferative diseases, myelodysplastic syndromes,acute myeloid leukemia, and acute biphenotypic leukemia.

Generally, cell proliferative disorders treatable with the compoundsdisclosed herein relate to any disorder characterized by aberrant cellproliferation. These include various tumors and cancers, benign ormalignant, metastatic or non-metastatic. Specific properties of cancers,such as tissue invasiveness or metastasis, can be targeted using themethods described herein. Cell proliferative disorders include a varietyof cancers, including, among others, breast cancer, ovarian cancer,renal cancer, gastrointestinal cancer, kidney cancer, bladder cancer,pancreatic cancer, lung squamous carcinoma, and adenocarcinoma.

In some embodiments, the cell proliferative disorder treated is ahematopoietic neoplasm, which is aberrant growth of cells of thehematopoietic system. Hematopoietic malignancies can have its origins inpluripotent stem cells, multipotent progenitor cells, oligopotentcommitted progenitor cells, precursor cells, and terminallydifferentiated cells involved in hematopoiesis. Some hematologicalmalignancies are believed to arise from hematopoietic stem cells, whichhave the ability for self renewal. For instance, cells capable ofdeveloping specific subtypes of acute myeloid leukemia (AML) upontransplantation display the cell surface markers of hematopoietic stemcells, implicating hematopoietic stem cells as the source of leukemiccells. Blast cells that do not have a cell marker characteristic ofhematopoietic stem cells appear to be incapable of establishing tumorsupon transplantation (Blaire et al., 1997, Blood 89:3104-3112). The stemcell origin of certain hematological malignancies also finds support inthe observation that specific chromosomal abnormalities associated withparticular types of leukemia can be found in normal cells ofhematopoietic lineage as well as leukemic blast cells. For instance, thereciprocal translocation t(9q34;22q11) associated with approximately 95%of chronic myelogenous leukemia appears to be present in cells of themyeloid, erythroid, and lymphoid lineage, suggesting that thechromosomal aberration originates in hematopoietic stem cells. Asubgroup of cells in certain types of CML displays the cell markerphenotype of hematopoietic stem cells.

Although hematopoietic neoplasms often originate from stem cells,committed progenitor cells or more terminally differentiated cells of adevelopmental lineage can also be the source of some leukemias. Forexample, forced expression of the fusion protein Bcr/Abl (associatedwith chronic myelogenous leukemia) in common myeloid progenitor orgranulocyte/macrophage progenitor cells produces a leukemic-likecondition. Moreover, some chromosomal aberrations associated withsubtypes of leukemia are not found in the cell population with a markerphenotype of hematopoietic stem cells, but are found in a cellpopulation displaying markers of a more differentiated state of thehematopoietic pathway (Turhan et al., 1995, Blood 85:2154-2161). Thus,while committed progenitor cells and other differentiated cells may haveonly a limited potential for cell division, leukemic cells may haveacquired the ability to grow unregulated, in some instances mimickingthe self-renewal characteristics of hematopoietic stem cells (Passegueet al., Proc. Natl. Acad. Sci. USA, 2003, 100:11842-9).

In some embodiments, the hematopoietic neoplasm treated is a lymphoidneoplasm, where the abnormal cells are derived from and/or display thecharacteristic phenotype of cells of the lymphoid lineage. Lymphoidneoplasms can be subdivided into B-cell neoplasms, T and NK-cellneoplasms, and Hodgkin's lymphoma. B-cell neoplasms can be furthersubdivided into precursor B-cell neoplasm and mature/peripheral B-cellneoplasm. Exemplary B-cell neoplasms are precursor B-lymphoblasticleukemia/lymphoma (precursor B-cell acute lymphoblastic leukemia) whileexemplary mature/peripheral B-cell neoplasms are B-cell chroniclymphocytic leukemia/small lymphocytic lymphoma, B-cell prolymphocyticleukemia, lymphoplasmacytic lymphoma, splenic marginal zone B-celllymphoma, hairy cell leukemia, plasma cell myeloma/plasmacytoma,extranodal marginal zone B-cell lymphoma of MALT type, nodal marginalzone B-cell lymphoma, follicular lymphoma, mantle-cell lymphoma, diffuselarge B-cell lymphoma, mediastinal large B-cell lymphoma, primaryeffusion lymphoma, and Burkitt's lymphoma/Burkitt cell leukemia. T-celland Nk-cell neoplasms are further subdivided into precursor T-cellneoplasm and mature (peripheral) T-cell neoplasms. Exemplary precursorT-cell neoplasm is precursor T-lymphoblastic lymphoma/leukemia(precursor T-cell acute lymphoblastic leukemia) while exemplary mature(peripheral) T-cell neoplasms are T-cell prolymphocytic leukemia T-cellgranular lymphocytic leukemia, aggressive NK-cell leukemia, adult T-celllymphoma/leukemia (HTLV-1), extranodal NK/T-cell lymphoma, nasal type,enteropathy-type T-cell lymphoma, hepatosplenic gamma-delta T-celllymphoma, subcutaneous panniculitis-like T-cell lymphoma, Mycosisfungoides/Sezary syndrome, Anaplastic large-cell lymphoma, T/null cell,primary cutaneous type, Peripheral T-cell lymphoma, not otherwisecharacterized, Angioimmunoblastic T-cell lymphoma, Anaplastic large-celllymphoma, T/null cell, primary systemic type. The third member oflymphoid neoplasms is Hodgkin's lymphoma, also referred to as Hodgkin'sdisease. Exemplary diagnosis of this class that can be treated with thecompounds include, among others, nodular lymphocyte-predominantHodgkin's lymphoma, and various classical forms of Hodgkin's disease,exemplary members of which are Nodular sclerosis Hodgkin's lymphoma(grades 1 and 2), Lymphocyte-rich classical Hodgkin's lymphoma, Mixedcellularity Hodgkin's lymphoma, and Lymphocyte depletion Hodgkin'slymphoma. In various embodiments, any of the lymphoid neoplasms that areassociated with aberrant JAK activity can be treated with the JAKinhibitory compounds.

In some embodiments, the hematopoietic neoplasm treated is a myeloidneoplasm. This group comprises a large class of cell proliferativedisorders involving or displaying the characteristic phenotype of thecells of the myeloid lineage. Myeloid neoplasms can be subdivided intomyeloproliferative diseases, myelodysplastic/myeloproliferativediseases, myelodysplastic syndromes, and acute myeloid leukemias.Exemplary myeloproliferative diseases are chronic myelogenous leukemia(e.g., Philadelphia chromosome positive (t(9;22)(qq34;q11)), chronicneutrophilic leukemia, chronic eosinophilic leukemia/hypereosinophilicsyndrome, chronic idiopathic myelofibrosis, polycythemia vera, andessential thrombocythemia. Exemplary myelodysplastic/myeloproliferativediseases are chronic myelomonocytic leukemia, atypical chronicmyelogenous leukemia, and juvenile myelomonocytic leukemia. Exemplarymyelodysplastic syndromes are refractory anemia, with ringedsideroblasts and without ringed sideroblasts, refractory cytopenia(myelodysplastic syndrome) with multilineage dysplasia, refractoryanemia (myelodysplastic syndrome) with excess blasts, 5q-syndrome, andmyelodysplastic syndrome. In various embodiments, any of the myeloidneoplasms that are associated with aberrant JAK activity can be treatedwith the JAK inhibitory compounds.

In some embodiments, the JAK inhibitory compounds can be used to treatAcute myeloid leukemias (AML), which represent a large class of myeloidneoplasms having its own subdivision of disorders. These subdivisionsinclude, among others, AMLs with recurrent cytogenetic translocations,AML with multilineage dysplasia, and other AML not otherwisecategorized. Exemplary AMLs with recurrent cytogenetic translocationsinclude, among others, AML with t(8;21)(q22;q22), AML1(CBF-alpha)/ETO,Acute promyelocytic leukemia (AML with t(15;17)(q22;q11-12) andvariants, PML/RAR-alpha), AML with abnormal bone marrow eosinophils(inv(16)(p13q22) or t(16;16)(p13;q11), CBFb/MYH11X), and AML with 11q23(MLL) abnormalities. Exemplary AML with multilineage dysplasia are thosethat are associated with or without prior myelodysplastic syndrome.Other acute myeloid leukemias not classified within any definable groupinclude, AML minimally differentiated, AML without maturation, AML withmaturation, Acute myelomonocytic leukemia, Acute monocytic leukemia,Acute erythroid leukemia, Acute megakaryocytic leukemia, Acutebasophilic leukemia, and Acute panmyelosis with myelofibrosis.

One means of assaying for such inhibition is detection of the effect ofthe 2,4-pyrimidinediamine compounds on the upregulation of downstreamgene products. In the Ramos/IL4 assay, B-cells are stimulated with thecytokine Interleukin-4 (IL-4) leading to the activation of the JAK/Statpathway through phosphorylation of the JAK family kinases, JAK1 andJAK3, which in turn phosphorylate and activate the transcription factorStat-6. One of the genes upregulated by activated Stat-6 is the lowaffinity IgE receptor, CD23. To study the effect of inhibitors (e.g.,the 2,4-substituted pyrimindinediamine compounds described herein) onthe JAK1 and JAK3 kinases, human Ramos B cells are stimulated with humanIL-4. 20 to 24 hours post stimulation, cells are stained forupregulation of CD23 and analyzed using flow cytometry (FACS). Areduction of the amount of CD23 present compared to control conditionsindicates the test compound actively inhibits the JAK kinase pathway. Anexemplary assay of this type is described in greater detail in Example3.

The activity of the active compounds of the invention may further becharacterized by assaying the effect of the 2,4-pyrimidinediaminecompounds described herein on the proliferative response of primaryhuman T-cells. In this assay, primary human T-cells derived fromperipheral blood and pre-activated through stimulation of the T-cellreceptor and CD28, proliferate in culture in response to the cytokineInterleukin-2 (IL-2). This proliferative response is dependent on theactivation of JAK1 and JAK3 tyrosine kinases, which phosphorylate andactivate the transcription factor Stat-5. The primary human T-cells areincubated with the 2,4-pyrimidinediamine compounds in the presence ofIL-2 for 72 hours, and at the assay endpoint intracellular ATPconcentrations are measured to assess cell viability. A reduction incell proliferation compared to control conditions is indicative ofinhibition of the JAK kinase pathway. An exemplary assay of this type isdescribed in greater detail in Example 4.

The activity of the compounds of the invention may additionally becharacterized by assaying the effect of the 2,4-pyrimidinediaminecompounds described herein on A549 lung epithelial cells and U937 cells.A549 lung epithelial cells and U937 cells up-regulate ICAM-1 (CD54)surface expression in response to a variety of different stimuli.Therefore, using ICAM-1 expression as readout, test compound effects ondifferent signaling pathways can be assessed in the same cell type.Stimulation with IL-1β through the IL-1β receptor activates theTRAF6/NFκB pathway resulting in up-regulation of ICAM-1. IFNγ inducesICAM-1 up-regulation through activation of the JAK1/JAK2 pathway. Theup-regulation of ICAM-1 can be quantified by flow cytometry across acompound dose curve and EC₅₀ values are calculated. Exemplary assays ofthis type are described in greater detail in Examples 5 and 6.

Active compounds as described herein generally inhibit the JAK kinasepathway with an IC₅₀ in the range of about 1 mM or less, as measured inthe assays described herein. Of course, skilled artisans will appreciatethat compounds which exhibit lower IC₅₀s, (on the order, for example, of100 μM, 75 μM, 50 μM, 40 μM, 30 μM, 20 μM, 15 μM, 10 μM, 5 μM, 1 μM, 500nM, 100 nM, 10 nM, 1 nM, or even lower) can be particularly useful intherapeutic applications. In instances where activity specific to aparticular cell type is desired, the compound can be assayed foractivity with the desired cell type and counter-screened for a lack ofactivity against other cell types. The desired degree of “inactivity” insuch counter screens, or the desired ratio of activity vs. inactivity,may vary for different situations and can be selected by the user.

The 2,4-pyrimidinediamine active compounds also typically inhibit IL-4stimulated expression of CD23 in B-cells with an 10₅₀ in the range ofabout 20 μM or less, typically in the range of about 10 μM, 1 μM, 500nM, 100 nM, 10 nM, 1 nM, or even lower. A suitable assay that can beused is the assay described in Example 3, “Assay for Ramos B-Cell LineStimulated with IL-4.” In certain embodiments, the active2,4-pyrimidinediamine compounds have an IC₅₀ of less than or equal to 5μM, greater than 5 μM but less than 20 μM, greater than 20 μM, orgreater than 20 μM but less than 50 μM in the assay described in Example3.

Additionally, the 2,4-pyrimidinediamine active compounds typicallyinhibit an activity of human primary T-cells with an IC₅₀ in the rangeof about 20 μM or less, typically in the range of about 10 μM, 1 μM, 500nM, 100 nM, 10 nM, 1 nM, or even lower. The IC₅₀ against human primaryT-cells can be determined in a standard in vitro assay with isolatedhuman primary T-cells. A suitable assay that can be used is the assaydescribed in Example 4, “Primary Human T-cell Proliferation AssayStimulated with IL-2.” In certain embodiments, the active2,4-pyrimidinediamine compounds have an IC₅₀ of less than or equal to 5μM, greater than 5 μM but less than 20 μM, greater than 20 μM, orgreater than 20 μM but less than 50 μM in the assay described in Example4.

The 2,4-pyrimidinediamine active compounds also typically inhibitexpression of ICAM1 (CD54) induced by IFNγ exposure in U937 or A549cells with an IC₅₀ in the range of about 20 μM or less, typically in therange of about 10 μM, 1 μM, 500 nM, 100 nM, 10 nM, 1 nM, or even lower.The IC₅₀ against expression of ICAM (CD54) in IFNγ stimulated cells canbe determined in a functional cellular assay with an isolated A549 orU937 cell line. Suitable assays that can be used are the assaysdescribed in Examples 5 and 6, “A549 Epithelial Line Stimulated withIFNγ” and “U937 IFNγ ICAM1 FACS Assay,” respectively. In certainembodiments, the active 2,4-pyrimidinediamine compounds have an IC₅₀ ofless than or equal to 20 μM, greater than 20 μM, or greater than 20 μMbut less than 50 μM in the assays described in Example 5 and 6.

In addition, the inhalation device is preferably practical, in the senseof being easy to use, small enough to carry conveniently, capable ofproviding multiple doses, and durable. Some specific examples ofcommercially available inhalation devices are Turbohaler (Astra,Wilmington, Del.), Rotahaler (Glaxo, Research Triangle Park, N.C.),Diskus (Glaxo, Research Triangle Park, N.C.), the Ultravent nebulizer(Mallinckrodt), the Acorn II nebulizer (Marquest Medical Products,Totowa, N.J.) the Ventolin metered dose inhaler (Glaxo, ResearchTriangle Park, N.C.), and the like. In one embodiment,2,4-pyrimidinediamine compounds can be delivered by a dry powder inhaleror a sprayer.

As those skilled in the art will recognize, the formulation of2,4-pyrimidinediamine compounds, the quantity of the formulationdelivered, and the duration of administration of a single dose depend onthe type of inhalation device employed as well as other factors. Forsome aerosol delivery systems, such as nebulizers, the frequency ofadministration and length of time for which the system is activated willdepend mainly on the concentration of 2,4-pyrimidinediamine compounds inthe aerosol. For example, shorter periods of administration can be usedat higher concentrations of 2,4-pyrimidinediamine compounds in thenebulizer solution. Devices such as metered dose inhalers can producehigher aerosol concentrations and can be operated for shorter periods todeliver the desired amount of 2,4-pyrimidinediamine compounds in someembodiments. Devices such as dry powder inhalers deliver active agentuntil a given charge of agent is expelled from the device. In this typeof inhaler, the amount of 2,4-pyrimidinediamine compounds in a givenquantity of the powder determines the dose delivered in a singleadministration. The formulation of 2,4-pyrimidinediamine is selected toyield the desired particle size in the chosen inhalation device.

Formulations of 2,4-pyrimidinediamine compounds for administration froma dry powder inhaler may typically include a finely divided dry powdercontaining 2,4-pyrimidinediamine compounds, but the powder can alsoinclude a bulking agent, buffer, carrier, excipient, another additive,or the like. Additives can be included in a dry powder formulation of2,4-pyrimidinediamine compounds, for example, to dilute the powder asrequired for delivery from the particular powder inhaler, to facilitateprocessing of the formulation, to provide advantageous powder propertiesto the formulation, to facilitate dispersion of the powder from theinhalation device, to stabilize to the formulation (e.g., antioxidantsor buffers), to provide taste to the formulation, or the like. Typicaladditives include mono-, di-, and polysaccharides; sugar alcohols andother polyols, such as, for example, lactose, glucose, raffinose,melezitose, lactitol, maltitol, trehalose, sucrose, mannitol, starch, orcombinations thereof; surfactants, such as sorbitols, diphosphatidylcholine, or lecithin; and the like.

The present invention also relates to a pharmaceutical compositionincluding 2,4-pyrimidinediamine compounds suitable for administration byinhalation. According to the invention, 2,4-pyrimidinediamine compoundscan be used for manufacturing a composition or medicament, includingmedicaments suitable for administration by inhalation. The inventionalso relates to methods for manufacturing compositions including2,4-pyrimidinediamine compounds in a form that is suitable foradministration, including administration by inhalation. For example, adry powder formulation can be manufactured in several ways, usingconventional techniques, such as described in any of the publicationsmentioned above and incorporated expressly herein by reference, and, forexample, Baker, et al., U.S. Pat. No. 5,700,904, the entire disclosureof which is incorporated expressly herein by reference. Particles in thesize range appropriate for maximal deposition in the lower respiratorytract can be made by micronizing, milling, or the like. And a liquidformulation can be manufactured by dissolving the 2,4-pyrimidinediaminecompounds in a suitable solvent, such as water, at an appropriate pH,including buffers or other excipients.

Pharmaceutical compositions comprising the 2,4-pyrimidinediaminecompounds described herein (or prodrugs thereof) can be manufactured bymeans of conventional mixing, dissolving, granulating, dragee-makinglevigating, emulsifying, encapsulating, entrapping, or lyophilizationprocesses. The compositions can be formulated in conventional mannerusing one or more physiologically acceptable carriers, diluents,excipients, or auxiliaries which facilitate processing of the activecompounds into preparations which can be used pharmaceutically.

For ocular administration, the 2,4-pyrimidinediamine compound(s) orprodrug(s) can be formulated as a solution, emulsion, suspension, etc.,suitable for administration to the eye. A variety of vehicles suitablefor administering compounds to the eye are known in the art. Specificnon-limiting examples are described in U.S. Pat. Nos. 6,261,547;6,197,934; 6,056,950; 5,800,807; 5,776,445; 5,698,219; 5,521,222;5,403,841; 5,077,033; 4,882,150; and 4,738,851.

For prolonged delivery, the 2,4-pyrimidinediamine compound(s) orprodrug(s) can be formulated as a depot preparation for administrationby implantation or intramuscular injection. The active ingredient can beformulated with suitable polymeric or hydrophobic materials (e.g., as anemulsion in an acceptable oil) or ion exchange resins, or as sparinglysoluble derivatives (e.g., as a sparingly soluble salt). Alternatively,transdermal delivery systems manufactured as an adhesive disc or patchwhich slowly releases the active compound(s) for percutaneous absorptioncan be used. To this end, permeation enhancers can be used to facilitatetransdermal penetration of the active compound(s). Suitable transdermalpatches are described in, for example, U.S. Pat. Nos. 5,407,713;5,352,456; 5,332,213; 5,336,168; 5,290,561; 5,254,346; 5,164,189;5,163,899; 5,088,977; 5,087,240; 5,008,110; and 4,921,475.

Alternatively, other pharmaceutical delivery systems can be employed.Liposomes and emulsions are well-known examples of delivery vehiclesthat can be used to deliver active compound(s) or prodrug(s). Certainorganic solvents such as dimethylsulfoxide (DMSO) may also be employed,although usually at the cost of greater toxicity.

The pharmaceutical compositions may, if desired, be presented in a packor dispenser device which may contain one or more unit dosage formscontaining the active compound(s). The pack may, for example, comprisemetal or plastic foil, such as a blister pack. The pack or dispenserdevice can be accompanied by instructions for administration.

The 2,4-pyrimidinediamine compound(s) or prodrug(s) described herein, orcompositions thereof, will generally be used in an amount effective toachieve the intended result, for example, in an amount effective totreat or prevent the particular condition being treated. The compound(s)can be administered therapeutically to achieve therapeutic benefit orprophylactically to achieve prophylactic benefit. By therapeutic benefitis meant eradication or amelioration of the underlying disorder beingtreated and/or eradication or amelioration of one or more of thesymptoms associated with the underlying disorder such that the patientreports an improvement in feeling or condition, notwithstanding that thepatient may still be afflicted with the underlying disorder. Forexample, administration of a compound to a patient suffering from anallergy provides therapeutic benefit not only when the underlyingallergic response is eradicated or ameliorated, but also when thepatient reports a decrease in the severity or duration of the symptomsassociated with the allergy following exposure to the allergen. Asanother example, therapeutic benefit in the context of asthma includesan improvement in respiration following the onset of an asthmatic attackor a reduction in the frequency or severity of asthmatic episodes. Asanother specific example, therapeutic benefit in the context oftransplantation rejection includes the ability to alleviate an acuterejection episode, such as, for example, HVGR or GVHR, or the ability toprolong the time period between onset of acute rejection episodes and/oronset of chronic rejection. Therapeutic benefit also includes halting orslowing the progression of the disease, regardless of whetherimprovement is realized.

The amount of compound administered will depend upon a variety offactors, including, for example, the particular condition being treated,the mode of administration, the severity of the condition being treated,the age and weight of the patient, the bioavailability of the particularactive compound. Determination of an effective dosage is well within thecapabilities of those skilled in the art.

As known by those of skill in the art, the preferred dosage of2,4-pyrimidinediamine compounds will also depend on the age, weight,general health, and severity of the condition of the individual beingtreated. Dosage may also need to be tailored to the sex of theindividual and/or the lung capacity of the individual, whereadministered by inhalation. Dosage may also be tailored to individualssuffering from more than one condition or those individuals who haveadditional conditions which affect lung capacity and the ability tobreathe normally, for example, emphysema, bronchitis, pneumonia, andrespiratory infections. Dosage, and frequency of administration of thecompounds or prodrugs thereof, will also depend on whether the compoundsare formulated for treatment of acute episodes of a condition or for theprophylactic treatment of a disorder. For example, acute episodes ofallergic conditions, including allergy-related asthma, transplantrejection, etc. A skilled practitioner will be able to determine theoptimal dose for a particular individual.

For prophylactic administration, the compound can be administered to apatient at risk of developing one of the previously describedconditions. For example, if it is unknown whether a patient is allergicto a particular drug, the compound can be administered prior toadministration of the drug to avoid or ameliorate an allergic responseto the drug. Alternatively, prophylactic administration can be appliedto avoid the onset of symptoms in a patient diagnosed with theunderlying disorder. For example, a compound can be administered to anallergy sufferer prior to expected exposure to the allergen. Compoundsmay also be administered prophylactically to healthy individuals who arerepeatedly exposed to agents known to one of the above-describedmaladies to prevent the onset of the disorder. For example, a compoundcan be administered to a healthy individual who is repeatedly exposed toan allergen known to induce allergies, such as latex, in an effort toprevent the individual from developing an allergy. Alternatively, acompound can be administered to a patient suffering from asthma prior topartaking in activities which trigger asthma attacks to lessen theseverity of, or avoid altogether, an asthmatic episode.

In the context of transplant rejection, the compound can be administeredwhile the patient is not having an acute rejection reaction to avoid theonset of rejection and/or prior to the appearance of clinicalindications of chronic rejection. The compound can be administeredsystemically to the patient as well as administered to the tissue ororgan prior to transplanting the tissue or organ in the patient.

The amount of compound administered will depend upon a variety offactors, including, for example, the particular indication beingtreated, the mode of administration, whether the desired benefit isprophylactic or therapeutic, the severity of the indication beingtreated and the age and weight of the patient, and the bioavailabilityof the particular active compound. Determination of an effective dosageis well within the capabilities of those skilled in the art.

Effective dosages can be estimated initially from in vitro assays. Forexample, an initial dosage for use in animals can be formulated toachieve a circulating blood or serum concentration of active compoundthat is at or above an IC50 of the particular compound as measured in asin vitro assay. Calculating dosages to achieve such circulating blood orserum concentrations taking into account the bioavailability of theparticular compound is well within the capabilities of skilled artisans.For guidance, the reader is referred to Fingl & Woodbury, “GeneralPrinciples,” In: Goodman and Gilman's The Pharmaceutical Basis ofTherapeutics, Chapter 1, pp. 1-46, latest edition, Pergamagon Press, andthe references cited therein.

Initial dosages can also be estimated from in vivo data, such as animalmodels. Animal models useful for testing the efficacy of compounds totreat or prevent the various diseases described above are well-known inthe art. Suitable animal models of hypersensitivity or allergicreactions are described in Foster, (1995) Allergy 50(21 Suppl):6-9,discussion 34-38 and Tumas et al., (2001), J. Allergy Clin. Immunol.107(6):1025-1033. Suitable animal models of allergic rhinitis aredescribed in Szelenyi et al., (2000), Arzneimittelforschung50(11):1037-42; Kawaguchi et al., (1994), Clin. Exp. Allergy24(3):238-244 and Sugimoto et al., (2000), Immunopharmacology 48(1):1-7.Suitable animal models of allergic conjunctivitis are described inCarreras et al., (1993), Br. J. Ophthalmol. 77(8):509-514; Saiga et al.,(1992), Ophthalmic Res. 24(1):45-50; and Kunert et al., (2001), Invest.Ophthalmol. Vis. Sci. 42(11):2483-2489. Suitable animal models ofsystemic mastocytosis are described in O'Keefe et al., (1987), J. Vet.Intern. Med. 1(2):75-80 and Bean-Knudsen et al., (1989), Vet. Pathol.26(1):90-92. Suitable animal models of hyper IgE syndrome are describedin Claman et al., (1990), Clin. Immunol. Immunopathol. 56(1):46-53.Suitable animal models of B-cell lymphoma are described in Hough et al.,(1998), Proc. Natl. Acad. Sci. USA 95:13853-13858 and Hakim et al.,(1996), J. Immunol. 157(12):5503-5511. Suitable animal models of atopicdisorders such as atopic dermatitis, atopic eczema, and atopic asthmaare described in Chan et al., (2001), J. Invest. Dermatol.117(4):977-983 and Suto et al., (1999), Int. Arch. Allergy Immunol.120(Suppl 1):70-75. Suitable animal models of transplant rejection, suchas models of HVGR, are described in O'Shea et al., (2004), NatureReviews Drug Discovery 3:555-564; Cetkovic-Curlje & Tibbles, (2004),Current Pharmaceutical Design 10:1767-1784; and Chengelian et al.,(2003), Science 302:875-878. Ordinarily skilled artisans can routinelyadapt such information to determine dosages suitable for humanadministration.

Dosage amounts will typically be in the range of from about 0.0001 or0.001 or 0.01 mg/kg/day to about 100 mg/kg/day, but can be higher orlower, depending upon, among other factors, the activity of thecompound, its bioavailability, the mode of administration, and variousfactors discussed above. Dosage amount and interval can be adjustedindividually to provide plasma levels of the compound(s) which aresufficient to maintain therapeutic or prophylactic effect. For example,the compounds can be administered once per week, several times per week(e.g., every other day), once per day, or multiple times per day,depending upon, among other things, the mode of administration, thespecific indication being treated, and the judgment of the prescribingphysician. In cases of local administration or selective uptake, such aslocal topical administration, the effective local concentration ofactive compound(s) may not be related to plasma concentration. Skilledartisans will be able to optimize effective local dosages without undueexperimentation.

Preferably, the compound(s) will provide therapeutic or prophylacticbenefit without causing substantial toxicity. Toxicity of thecompound(s) can be determined using standard pharmaceutical procedures.The dose ratio between toxic and therapeutic (or prophylactic) effect isthe therapeutic index. Compounds(s) that exhibit high therapeuticindices are preferred.

The foregoing disclosure pertaining to the dosage requirements for the2,4-substituted pyrimidinediamine compounds is pertinent to dosagesrequired for prodrugs, with the realization, apparent to the skilledartisan, that the amount of prodrug(s) administered will also dependupon a variety of factors, including, for example, the bioavailabilityof the particular prodrug(s) and the conversation rate and efficiencyinto active drug compound under the selected route of administration.Determination of an effective dosage of prodrug(s) for a particular useand mode of administration is well within the capabilities of thoseskilled in the art.

Effective dosages can be estimated initially from in vitro activity andmetabolism assays. For example, an initial dosage of prodrug for use inanimals can be formulated to achieve a circulating blood or serumconcentration of the metabolite active compound that is at or above anIC50 of the particular compound as measured in as in vitro assay, suchas the in vitro CHMC or BMMC and other in vitro assays described in U.S.application Ser.

F. General Synthesis of the Compounds of the Invention

The 2,4-pyrimidinediamine compounds and prodrugs of the invention may besynthesized via a variety of different synthetic routes usingcommercially available starting materials and/or starting materialsprepared by conventional synthetic methods. Suitable exemplary methodsthat may be routinely adapted to synthesize the 2,4-pyrimidinediaminecompounds and prodrugs of the invention are found in U.S. Pat. No.5,958,935, the disclosure of which is incorporated herein by reference.Specific examples describing the synthesis of numerous2,4-pyrimidinediamine compounds and prodrugs, as well as intermediatestherefore, are described in copending U.S. application Ser. No.10/355,543, filed Jan. 31, 2003 (US2004/0029902A1), the contents ofwhich are incorporated herein by reference. Suitable exemplary methodsthat may be routinely used and/or adapted to synthesize active2,4-substituted pyrimidinediamine compounds can also be found ininternational application Ser. No. PCT/US03/03022 filed Jan. 31, 2003(WO 03/063794), U.S. application Ser. No. 10/631,029 filed Jul. 29,2003, international application Serial No. PCT/US03/24087(WO2004/014382), U.S. application Ser. No. 10/903,263 filed Jul. 30,2004, and international application Serial No. PCT/US2004/24716(WO005/016893), the disclosures of which are incorporated herein byreference. All of the compounds described herein (including prodrugs)may be prepared by routine adaptation of these methods.

Specific exemplary synthetic methods for the 2,4-substitutedpyrimidinediamines described herein are also described in Examples 1 and2, below. Those of skill in the art will also be able to readily adaptthese examples for the synthesis of additional 2,4-substitutedpyrimidinediamines as described herein.

A variety of exemplary synthetic routes that can be used to synthesizethe 2,4-pyrimidinediamine compounds of the invention are described inSchemes (I)-(VII), below. These methods may be routinely adapted tosynthesize the 2,4-substituted pyrimidinediamine compounds and prodrugsdescribed herein.

In one exemplary embodiment, the compounds can be synthesized fromsubstituted or unsubstituted uracils as illustrated in Scheme (I),below:

In Scheme (I), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, X, and Y are asdefined herein. According to Scheme (I), uracil A-1 is dihalogenated atthe 2-and 4-positions using a standard halogenating agent such as POCl₃(or other standard halogenating agent) under standard conditions toyield 2,4-dichloropyrimidine A-2. Depending upon the X substituent, inpyrimidinediamine A-2, the chloride at the C4 position is more reactivetowards nucleophiles than the chloride at the C2 position. Thisdifferential reactivity can be exploited to synthesize2,4-pyrimidinediamines A-7 by first reacting 2,4-dichloropyrimidine A-2with one equivalent of amine A-3, yielding4N-substituted-2-chloro-4-pyrimidineamine A-4, followed by amine A-5 toyield a 2,4-pyrimidinediamine derivative A-6, where N4 nitrogen can beselectively alkylated to give compounds of formula A-7.

Typically, the C4 halide is more reactive towards nucleophiles, asillustrated in the Scheme. However, as will be recognized by skilledartisans, the identity of the X substituent may alter this reactivity.For example, when X is trifluoromethyl, a 50:50 mixture of4N-substituted-4-pyrimidineamine A-4 and the corresponding2N-substituted-2-pyrimidineamine is obtained. The regioselectivity ofthe reaction can also be controlled by adjusting the solvent and othersynthetic conditions (such as temperature), as is well-known in the art.

The reactions depicted in Scheme (I) may proceed more quickly when thereaction mixtures are heated via microwave. When heating in thisfashion, the following conditions may be used: heat to 175° C. inethanol for 5-20 min. in a Smith Reactor (Personal Chemistry, Uppsala,Sweden) in a sealed tube (at 20 bar pressure).

The uracil 1 starting materials may be purchased from commercial sourcesor prepared using standard techniques of organic chemistry. Commerciallyavailable uracils that can be used as starting materials in Scheme (I)include, by way of example and not limitation, uracil (Aldrich#13,078-8; CAS Registry 66-22-8); 5-bromouracil (Aldrich #85,247-3; CASRegistry 51-20-7; 5-fluorouracil (Aldrich #85,847-1; CAS Registry51-21-8); 5-iodouracil (Aldrich #85,785-8; CAS Registry 696-07-1);5-nitrouracil (Aldrich #85,276-7; CAS Registry 611-08-5);5-(trifluoromethyl)-uracil (Aldrich #22,327-1; CAS Registry 54-20-6).Additional 5-substituted uracils are available from GeneralIntermediates of Canada, Inc., Edmonton, CA and/or Interchim, Cedex,France, or may be prepared using standard techniques. Myriad textbookreferences teaching suitable synthetic methods are provided infra.

Amines A-3 and A-5 may be purchased from commercial sources or,alternatively, may be synthesized utilizing standard techniques. Forexample, suitable amines may be synthesized from nitro precursors usingstandard chemistry. Specific exemplary reactions are provided in theExamples section. See also Vogel, 1989, Practical Organic Chemistry,Addison Wesley Longman, Ltd. and John Wiley & Sons, Inc.

Skilled artisans will recognize that in some instances, amines A-3 andA-5 and/or substituent X on uracil A-1 may include functional groupsthat require protection during synthesis. The exact identity of anyprotecting group(s) used will depend upon the identity of the functionalgroup being protected, and will be apparent to those of skill in theart. Guidance for selecting appropriate protecting groups, as well assynthetic strategies for their attachment and removal, may be found, forexample, in Greene & Wuts, Protective Groups in Organic Synthesis, 3dEdition, John Wiley & Sons, Inc., New York (1999) and the referencescited therein (hereinafter “Greene & Wuts”).

Thus, protecting group refers to a group of atoms that, when attached toa reactive functional group in a molecule, mask, reduce or prevent thereactivity of the functional group. Typically, a protecting group may beselectively removed as desired during the course of a synthesis.Examples of protecting groups can be found in Greene and Wuts, asmentioned above, and additionally, in Harrison et al., Compendium ofSynthetic Organic Methods, Vols. 1-8, 1971-1996, John Wiley & Sons, NY.Representative amino protecting groups include, but are not limited to,formyl, acetyl, trifluoroacetyl, benzyl, benzyloxycarbonyl (“CBZ”),tert-butoxycarbonyl (“Boc”), trimethylsilyl (“TMS”),2-trimethylsilyl-ethanesulfonyl (“TES”), trityl and substituted tritylgroups, allyloxycarbonyl, 9-fluorenylmethyloxycarbonyl (“FMOC”),nitro-veratryloxycarbonyl (“NVOC”) and the like. Representative hydroxylprotecting groups include, but are not limited to, those where thehydroxyl group is either acylated to form acetate and benzoate esters oralkylated to form benzyl and trityl ethers, as well as alkyl ethers,tetrahydropyranyl ethers, trialkylsilyl ethers (e.g., TMS or TIPPSgroups) and allyl ethers.

A specific embodiment of Scheme (I) utilizing 5-fluorouracil (Aldrich#32,937-1), compound A-8 where Y is hydrogen, as a starting material isillustrated in Scheme (Ia), below:

In Scheme (Ia), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, and Y are aspreviously defined for Scheme (I). Asymmetric2N,4N-disubstituted-5-fluoro-2,4-pyrimidinediamine A-11 may be obtainedby reacting 2,4-dichloro-5-fluoropyrimidine A-9 with one equivalent ofamine A-3 (to yield 2-chloro-N4-substituted-5-fluoro-4-pyrimidineamineA-10) followed by one or more equivalents of amine A-5.

In another exemplary embodiment, the 2,4-pyrimidinediamine compounds ofthe invention may be synthesized from substituted or unsubstitutedcytosines as illustrated in Schemes (IIa) and (IIb), below:

In Schemes (IIa) and (IIb), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, X, and Yare as previously defined for Scheme (I) and PG represents a protectinggroup. Referring to Scheme (IIa), the C4 exocyclic amine of cytosineA-12 is first protected with a suitable protecting group PG to yieldN4-protected cytosine A-13. For specific guidance regarding protectinggroups useful in this context, see Vorbrüggen and Ruh-Pohlenz, 2001,Handbook of Nucleoside Synthesis, John Wiley & Sons, NY, pp. 1-631(“Vorbrüggen”). Protected cytosine A-13 is halogenated at the C2position using a standard halogenation reagent under standard conditionsto yield 2-chloro-4N-protected-4-pyrimidineamine A-14. Reaction withamine A-5 gives A-15, which on deprotection of the C4 exocyclic amine,gives A-16. Reaction of A-16 with amine A-3 yields 2,4-pyrimidinediaminederivative A-6.

Alternatively, referring to Scheme (IIb), cytosine A-12 may be reactedwith amine A-3 or protected amine A-19 to yield N4-substituted cytosineA-17 or A-20, respectively. These substituted cytosines may then behalogenated as previously described, deprotected (in the case ofN4-substituted cytosine A-20) and reacted with amine A-5 to yield a2,4-pyrimidinediamine A-11a.

Commercially-available cytosines that may be used as starting materialsin Schemes (IIa) and (IIb) include, but are not limited to, cytosine(Aldrich #14,201-8; CAS Registry 71-30-7); N⁴-acetylcytosine (Aldrich#37,791-0; CAS Registry 14631-20-0); 5-fluorocytosine (Aldrich#27,159-4; CAS Registry 2022-85-7); and 5-(trifluoromethyl)-cytosine.Other suitable cytosines useful as starting materials in Schemes (IIa)are available from General Intermediates of Canada, Inc., Edmonton, CAand/or Interchim, Cedex, France, or may be prepared using standardtechniques. Myriad textbook references teaching suitable syntheticmethods are provided infra.

In still another exemplary embodiment, the 2,4-pyrimidinediaminecompounds of the invention may be synthesized from substituted orunsubstituted 2-amino-4-pyrimidinols as illustrated in Scheme (III),below:

In Scheme (III), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, X, and Y are aspreviously defined for Scheme (I) and LG is a leaving group as discussedin more detail in connection with Scheme IV, infra. Referring to Scheme(III), 2-amino-4-pyrimidinol A-22 is reacted with arylating agent A-23to yield N2-substituted-4-pyrimidinol A-24, which is then halogenated aspreviously described to yield N2-substituted-4-halo-2-pyrimidineamineA-25. Further reaction with amine A-3 affords a 2,4-pyrimidinediaminederivative A-6.

Suitable commercially-available 2-amino-4-pyrimidinols A-22 that can beused as starting materials in Scheme (III) are available from GeneralIntermediates of Canada, Inc., Edmonton, CA and/or Interchim, Cedex,France, or may be prepared using standard techniques.

Alternatively, the 2,4-pyrimidinediamine compounds of the invention maybe prepared from substituted or unsubstituted 4-amino-2-pyrimidinols asillustrated in Scheme (IV), below:

In Scheme (IV), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, X, and Y are aspreviously defined for Scheme (I). Referring to Scheme (IV), theC2-hydroxyl of 4-amino-2-pyrimidinol A-26 is more reactive towardsnucleophiles than the C4-amino such that reaction with amine A-5 yieldsN2-substituted-2,4-pyrimidinediamine A-27.

In still another exemplary embodiment, the 2,4-pyrimidinediaminecompounds of the invention can be prepared from2-chloro-4-aminopyrimidines or 2-amino-4-chloropyrimidines asillustrated in Scheme (V), below:

In Scheme (V), ring A, (R²)_(q), alk, (R³)_(p), R⁴, R⁵, X, and Y are asdefined for Scheme (I) and leaving group is as defined for Scheme (IV).Referring to Scheme (V), 2-amino-4-chloropyrimidine A-29 is reacted withamine A-3 to yield 4N-substituted-2,4-pyrimidinediamine A-30 which,following reaction with compound A-23 or amine A-5, yields aN2,N4-2,4-pyrimidinediamine derivative A-6. Alternatively,2-chloro-4-amino-pyrimidine A-31 may be reacted with compound A-28 togive compound A-32 which on reaction with amine A-5 yields A-6.

A variety of pyrimidines A-29 and A-31 suitable for use as startingmaterials in Scheme (V) are commercially available from GeneralIntermediates of Canada, Inc., Edmonton, Calif. and/or Interchim, Cedex,France, or may be prepared using standard techniques. Myriad textbookreferences teaching suitable synthetic methods are provided infra.

Alternatively, 4-chloro-2-pyrimidineamines A-29a may be prepared asillustrated in Scheme (Va):

In Scheme (Va), X is as previously defined for Scheme I. In Scheme (Va),dialdehyde A-33 is reacted with guanidine to yield 2-pyrimidineamineA-34. Reaction with a peracid such as m-chloroperbenzoic acid,trifluoroperacetic acid or urea hydrogen peroxide complex yields N-oxideA-35, which is then halogenated to give 4-chloro-2-pyrimidineamineA-29a. The corresponding 4-halo-2-pyrimidineamines may be obtained byusing suitable halogenation reagents.

In yet another exemplary embodiment, the 2,4-pyrimidinediamine compoundsof the invention can be prepared from substituted or unsubstituteduridines as illustrated in Scheme (VI), below:

In Scheme (VI), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, X, and Y are aspreviously defined for Scheme (I) and PG represents a protecting group,as discussed in connection with Scheme (IIb). According to Scheme (VI),uridine A-36 has a C4 reactive center such that reaction with amine A-3or protected amine A-19 yields N4-substituted cytidine A-37 or A-38,respectively. Acid-catalyzed deprotection of N4-substituted A-37 or A-38(when “PG” represents an acid-labile protecting group) yieldsN4-substituted cytosine A-39, which may be subsequently halogenated atthe C2-position and reacted with amine A-5 to yield a2,4-pyrimidinediamine derivative A-6.

Cytidines may also be used as starting materials in an analogous manner,as illustrated in Scheme (VII), below:

In Scheme (VII), ring A, (R²)_(q), (R³)_(p), R⁴, R⁵, X, and Y are aspreviously defined in Scheme (I) and PG represents a protecting group asdiscussed above. Referring to Scheme (VII), like uridine A-36, cytidineA-40 has a C4 reactive center such that reaction with amine A-3 orprotected amine A-19 yields N4-substituted cytidine A-37 or A-38,respectively. These cytidines A-37 and A-38 are then treated aspreviously described for Scheme (VI) to yield a 2,4-pyrimidinediaminederivative A-6.

Although Schemes (VI) and (VII) are exemplified with ribosylnucleosides,skilled artisans will appreciate that the corresponding 2′-deoxyribo and2′,3′-dideoxyribo nucleosides, as well as nucleosides including sugarsor sugar analogs other than ribose, would also work.

Although many of the synthetic schemes discussed above do not illustratethe use of protecting groups, skilled artisans will recognize that insome instances certain substituents, such as, for example, R2 and/or R4,may include functional groups requiring protection. The exact identityof the protecting group used will depend upon, among other things, theidentity of the functional group being protected and the reactionconditions used in the particular synthetic scheme and will be apparentto those of skill in the art. Guidance for selecting protecting groupsand their attachment and removal suitable for a particular applicationcan be found, for example, in Greene & Wuts, supra.

Prodrugs as described herein can be prepared by routine modification ofthe above-described methods. Alternatively, such prodrugs can beprepared by reacting a suitably protected 2,4-pyrimidinediamine 6 with asuitable progroup. Conditions for carrying out such reactions and fordeprotecting the product to yield a prodrugs as described herein arewell-known.

C. Example 3 Assay for Ramos B-Cell Line Stimulated with IL-4

B-cells stimulated with cytokine Interleukin-4 (IL-4) activate theJAK/Stat pathway through phosphorylation of the JAK family kinases,JAK-1 and JAK-3, which in turn phosphorylate and activate thetranscription factor Stat-6. One of the genes upregulated by activatedStat-6 is the low affinity IgE receptor, CD23. To study the effect ofinhibitors on the JAK family kinases, human Ramos B cells are stimulatedwith human IL-4.

The Ramos B-cell line was acquired from ATCC (ATCC Catalog No.CRL-1596). The cells were cultured in RPMI 1640 (Cellgro, MediaTech,Inc., Herndon, Va., Cat No. 10-040-CM) with 10% fetal bovine serum(FBS), heat inactivated (JRH Biosciences, Inc, Lenexa, Kans., Cat No.12106-500M) according to ATCC propagation protocol. Cells weremaintained at a density of 3.5×105. The day before the experiment, RamosB-cells were diluted to 3.5×105 cells/mL to ensure that they were in alogarithmic growth phase.

Cells were spun down and suspended in RPMI with 5% serum. 5×104 cellswere used per point in a 96-well tissue culture plate. Cells werepre-incubated with compound or DMSO (Sigma-Aldrich, St. Louis, Mo., CatNo. D2650) vehicle control for 1 hour in a 37° C. incubator. Cells werethen stimulated with IL-4 (Peprotech Inc., Rocky Hill, N.J., Cat No.200-04) for a final concentration of 50 units/mL for 20-24 hours. Cellswere then spun down and stained with anti-CD23-PE(BD Pharmingen, SanDiego, Calif., Cat No. 555711) and analyzed by FACS. Detection wasperformed using a BD LSR I System Flow Cytometer, purchased from BectonDickinson Biosciences of San Jose, Calif. The IC50 calculated based onthe results of this assay are provided in Table III.

D. Example 4 Primary Human T-Cell Proliferation Assay Stimulated withIL-2

Primary human T-cells derived from peripheral blood and pre-activatedthrough stimulation of the T-cell receptor and CD28 proliferate in vitroin response to the cytokine Interleukin-2 (IL-2). This proliferativeresponse is dependent on the activation of JAK-1 and JAK-3 tyrosinekinases, which phosphorylate and activate the transcription factorStat-5.

Human primary T cells were prepared as follows. Whole blood was obtainedfrom a healthy volunteer, mixed 1:1 with PBS, layered on to FicollHypaque (Amersham Pharmacia Biotech, Piscataway, N.J., Catalog#17-1440-03) in 2:1 blood/PBS:ficoll ratio and centrifuged for 30 min at4° C. at 1750 rpm. The lymphocytes at the serum: ficoll interface wererecovered and washed twice with 5 volumes of PBS. The cells wereresuspended in Yssel's medium (Gemini Bio-products, Woodland, Calif.,Catalog #400-103) containing 40 U/mL recombinant IL2 (R and D Systems,Minneapolis, Minn., Catalog #202-IL (20μg)) and seeded into a flaskpre-coated with 1 □g/mL anti-CD3 (BD Pharmingen, San Diego, Calif.,Catalog #555336) and 5 □g/mL anti-CD28 (Immunotech, Beckman Coulter ofBrea Calif., Catalog #IM1376). The primary T-cells were stimulated for 3to 4 days, then transferred to a fresh flask and maintained in RPMI with10% FBS and 40 U/mL IL-2.

Primary T-cells were washed twice with PBS to remove the IL-2 andresuspended in Yssel's medium at 2×106 cells/mL. 50 μL of cellsuspension containing 80 U/mL IL-2 was added to each well of a flatbottom 96 well black plate. For the unstimulated control, IL-2 wasomitted from the last column on the plate. Compounds were seriallydiluted in dimethyl sulfoxide (DMSO, 99.7% pure, cell culture tested,Sigma-Aldrich, St. Louis, Mo., Catalog No. D2650) from 5 mM in 3-folddilutions and then diluted 1:250 in Yssel's medium. 50 μL of 2× compoundwas added per well in duplicate and the cells were allowed toproliferate for 72 hours at 37° C.

Proliferation was measured using CellTiter-Glo® Luminescent CellViability Assay (Promega), which determines the number of viable cellsin culture based on quantitation of the ATP present, as an indicator ofmetabolically active cells. The substrate was thawed and allowed to cometo room temperature. After mixing the Cell Titer-Glo reagent and diluenttogether, 100 μL was added to each well. The plates were mixed on anorbital shaker for two minutes to induce lysis and incubated at roomtemperature for an additional ten minutes to allow the signal toequilibrate. Detection was performed using a Wallac Victor2 1420multilabel counter purchased from Perkin Elmer, Shelton, Conn. The IC50calculated based on the results of this assay are provided in Table III.

E. Example 5 A549 Epithelial Line Stimulated with IFNγ

A549 lung epithelial cells up-regulate ICAM-1 (CD54) surface expressionin response to a variety of different stimuli. Therefore, using ICAM-1expression as readout, compound effects on different signaling pathwayscan be assessed in the same cell type. IFNγ up-regulates ICAM-1 throughactivation of the JAK/Stat pathway. In this example, the up-regulationof ICAM-1 by IFNγ was assessed.

The A549 lung epithelial carcinoma cell line originated from theAmerican Type Culture Collection. Routine culturing was with F12K media(Mediatech Inc., Lenexa, Kans., Cat. No. 10-025-CV) with 10% fetalbovine serum, 100 I.U. penicillin and 100 ng/mL streptomycin (completeF12k media). Cells were incubated in a humidified atmosphere of 5% CO2at 37° C. Prior to use in the assay, A549 cells were washed with PBS andtrypsinized (Mediatech Inc., Cat. No. 25-052-CI) to lift the cells. Thetrypsin cell suspension was neutralized with complete F12K media andcentrifuged to pellet the cells. The cell pellet was resuspended incomplete F12K media at a concentration of 2.0×105/mL. Cells were seededat 20,000 per well, 100 μL total volume, in a flat bottom tissue cultureplate and allowed to adhere overnight.

On day two, A549 cells were pre-incubated with a 2,4-pyrimidinediaminetest compound or DMSO (control) (Sigma-Aldrich, St. Louis, Mo., CatalogNo. D2650) for 1 hour. The cells were then stimulated with IFNγ (75ng/mL) (Peprotech Inc., Rocky Hill, N.J., Cat. No. 300-02) and allowedto incubate for 24 hours. The final test compound dose range was 30 μMto 14 nM in 200 μL F12K media containing 5% FBS, 0.3% DMSO.

On day three, the cell media was removed and the cells were washed with200 μL PBS (phosphate buffered saline). Each well was trypsinized todissociate the cells, then neutralized by addition of 200 μL completeF12K media. Cells were pelleted and stained with an APC conjugated mouseanti-human ICAM-1 (CD54) (BD Pharmingen, San Diego, Calif., Catalog#559771) antibody for 20 minutes at 4° C. Cells were washed with icecold FACS buffer (PBS+2% FBS) and surface ICAM-1 expression was analyzedby flow cytometry. Detection was performed using a BD LSR I System FlowCytometer, purchased from BD Biosciences of San Jose, Calif. Events weregated for live scatter and the geometric mean was calculated(Becton-Dickinson CellQuest software version 3.3, Franklin Lakes, N.J.).Geometric means were plotted against the compound concentration togenerate a dose response curve. The IC50 calculated based on the resultsof this assay are provided in Table III.

F. Example 6 U937 IFNγ ICAM1 FACS Assay

U937 human monocytic cells up-regulate ICAM-1 (CD54) surface expressionin response to a variety of different stimuli. Therefore, using ICAM-1expression as readout, compound effects on different signaling pathwayscan be assessed in the same cell type. IFNγ up-regulates ICAM-1 throughactivation of the JAK/Stat pathway. In this example, the up-regulationof ICAM-1 by IFNγ was assessed.

The U937 human monocytic cell line was obtained from ATCC of Rockville,Md., catalog number CRL-1593.2, and cultured in RPM1-1640 mediumcontaining 10% (v/v) FCS. U937 cells were grown in 10% RPMI. The cellswere then plated at a concentration of 100,000 cells per 160 μL in 96well flat bottom plates. The test compounds were then diluted asfollows: 10 mM test compound was diluted 1:5 in DMSO (3 μL 10 mM testcompound in 12 μL DMSO), followed by a 1:3 serial dilution of testcompound in DMSO (6 μL test compound serially diluted into 12 μL DMSO togive 3-fold dilutions). Then 4 μL of test compound was transferred to 76μL of 10% RPMI resulting in a 10× solution (100 μM test compound, 5%DMSO). For control wells, 4 μL of DMSO was diluted into 76 μL 10% RPMI.

The assay was performed in duplicate with 8 points (8 3-fold dilutionconcentrations from 10 μl) and with 4 wells of DMSO only (control wells)under stimulated conditions and 4 wells of DMSO only under unstimulatedconditions.

The diluted compound plate was mixed 2× using a multimek (BeckmanCoulter of Brea, Calif.) and then 20 μL of the diluted compounds wastransferred to the 96 well plate containing 160 μL of cells, which werethen mixed again twice at low speeds. The cells and compounds were thenpre-incubated for 30 minutes at 37° C. with 5% CO2.

The 10× stimulation mix was made by preparing a 100 ng/mL solution ofhuman IFNγ in 10% RPMI. The cells and compound were then stimulated with20 μL of IFNγ stimulation mix to give a final concentration of 10 ng/mLIFNγ, 10 μM test compound, and 0.5% DMSO. The cells were kept underconditions for stimulation for 18-24 hours at 37° C. with 5% CO2.

The cells were transferred to a 96 well round bottom plate for stainingand then kept on ice for the duration of the staining procedure. Cellswere spun down at 1000 rpm for 5 minutes at 4° C., following which thesupernatant was removed. Following removal of the supernatant, 1 μL APCconjugated mouse anti-human ICAM-1 antibody was added per 100 μL FACSbuffer. The cells were then incubated on ice in the dark for 30 minutes.Following incubation, 150 μL of FACS buffer was added and the cells werecentrifuged at 1000 rpm for 5 minutes at 4° C., following which thesupernatant was removed. After removal of the supernatant, 200 μL ofFACS buffer was added and the cells were resuspended. After suspension,the cells were centrifuged at 1000 rpm for 5 min at 4° C. Supernatantwas then removed prior to resuspension of the cells in 150 μL FACSbuffer.

Detection was performed using a BD LSR I System Flow Cytometer,purchased from BD Biosciences of San Jose, Calif. The live cells weregated for live scatter and the geometric mean of ICAM-APC was measured(Becton-Dickinson CellQuest software version 3.3, Franklin Lakes, N.J.).Both % live cells and ICAM-1 expression was analyzed. The assays for thetest compounds were carried out in parallel with a control compound ofknown activity. The EC50 for the control compound is typically 40-100nM. The IC50 calculated based on the results of this assay are providedin Table XVI.
